CHAPTER 1

CORROSION PREVENTION AND CONTORL PROGRAMS 1000. INTRODUCTION 1. Background. I MEF Operating Forces operate daily and deploy in corrosive environments. As a consequence, corrosion of equipment presents one of the greatest challenges to the readiness and capability of I MEF equipment that we face. To combat this challenge, corrosion prevention and control must be an integral part of the preventive maintenance effort in order to prevent degradation of I MEF equipment to the point it is unserviceable or unsuitable for use. While corrosion cannot be stopped in total due to our operating environment and the design of our equipment, a robust CPAC Program will ameliorate the affects of corrosion thereby extending useful service life of equipment, conserving resources, improving readiness and sustaining capability. 2. With few exceptions, equipment in use by I MEF Operating Forces is not designed with corrosion prevention in mind. Future acquisitions such as the High Mobility Multi-purpose Wheeled Vehicle (HMMWV) replacement, Medium Tactical Vehicle Replacement (MTVR), and the Advanced Amphibious Assault Vehicle (AAAV) hold promise in the area of corrosion resistance. Until these and other new corrosion resistant equipment acquisitions are fielded, corrosion prevention and control will continue to challenge us and will become even more difficult as non-replaced equipment continues to age and our depot maintenance capability continues to diminish. These factors alone demand aggressive action on our part to implement and execute effective CPAC Programs. 3. Formalized CPAC programs have historically not been developed and applied. This SOP reverses that trend. All I MEF organizations must develop and execute a comprehensive CPAC Program down to the individual equipment operator. We have no choice in this matter. 1001. DEVELOPING A CPAC PROGRAM 1. CPAC Program development should occur no differently than any other maintenance or maintenance management related program. Reference (a) should serve as a model for CPAC Program development. Figure 1-1 on page 1-14 of reference (a) is a superb template around which to design a CPAC Program. A successful CPAC Program will be built around the elements of Command, Resources, Production, and Information.

2. As with implementation of any new program, an organization cannot map where it is going unless it knows where it has been and where it currently is. Simply put, an organization needs to Baseline its current corrosion problem in order to determine its priority of work in achieving the highest state of CPAC readiness possible and to also determine the best manner in which to execute its CPAC program. The Base-lining effort is best accomplished by a thorough one hundred percent inspection of all the organization’s equipment. Equipment should then be categorized per paragraph 1001.3 following. The results of this effort will be the baseline from which the success organization’s CPAC Program will be measured. Accordingly, all I MEF organizations will baseline the extent of equipment corrosion through a thorough and rigorous inspection upon receipt of this order. This process is to be repeated annually on or as near as possible to the anniversary date of the initial base lining effort. 3. I MEF has adopted a five-category system to classify the extent of corrosion existing for each item of equipment. The corrosion categories and their definitions are depicted in figure 1-1. The forthcoming MCO 4790.18 will also list a corrosion categorization system that contains four Alpha-designated categories. The I MEF categorization system provides a greater level of detail and will be the standard used by I MEF organizations. Appendix C provides a MCO 4790.18 – ForO 4795.1 corrosion categorization conversion chart. 4. Once a CPAC Program has been developed, a comprehensive training plan must then be developed and implemented in order to ensure success. Training can be accomplished in many ways such as classroom instruction, hands-on practical application, instruction by outside experts, and so on. All the above methods of training should be employed in order to achieve a balanced and effective training program. Classroom training alone will likely not achieve the desired level of expertise among an organization’s Marines. The organization’s Maintenance Management Officer (MMO) must also ensure that CPAC training is included in the training plan along with other maintenance and maintenance management related training topics and that the training is documented. Particular attention to training of Marine Expeditionary Unit (MEU) organizations is especially important, as many of these organizations will be subjected where the environment does not pose the same CPAC challenges, as does the environment in California. 5. The key to CPAC Program continuity is comprehensively developed SOP(s), Desktop Procedures, and Turnover Files. Whether an organization uses this SOP and adds its own unique policies, procedures and instructions as an Appendix or produces its own SOP, the SOP is the foundation of the CPAC Program. CPAC specific 1-4

CPAC SOP 1001 Desktop Procedures and Turnover files may be developed or CPAC Program requirements may be included in existing maintenance management related documents of this type. Whatever method is selected for documenting CPAC Program requirements and procedures, Desktop Procedures and Turnover Files must cover CPAC Procedures in sufficient detail to ensure continuity of program execution when key Marines leave the organization. CATEGORY DEFINITION GOAL Corrosion Condition 1 (CC-1)

Requires little or no effort. Is in the best condition with regard to corrosion.

The goal at this level is maintain the end item as CC-1

Corrosion Condition 2 (CC-2)

Requires surface preparation and spot paint at the operator and/or organizational level.

The goal of this effort should be to return this end item to CC-1.


Requires effort beyond the operator level and will require assistance at the mechanic/technician level beyond the organic level. Example: Spot painting has arrested the corrosion, but the vehicle requires complete repainting and overcoat. Must be managed by the Unit Commander and inducted into the Intermediate Maintenance Activity (IMA) IMA CRF for painting.

The goal of this effort is to schedule the end item into the IMA CRF and return the end item to CC-1


Requires repair to sheet metal or major frame components beyond the organizational level and must inducted into IMA prior to induction into the IMA CRF. Example: Chassis frame rails on HUMMVs, or support frames on cargo trailers.

The goal of this effort is to immediately induct this end item into the Intermediate Maintenance Activity and manage the repairs through the IMA CRF.


Is degraded to a degree that requires replacement of the end item based on the deterioration caused by corrosion.

The goal of this effort is to replace the end item

1003 CPAC SOP 1002. DESIGNATION AND ASSIGNMENT OF CPAC PROGRAM COORDINATOR 1. Focus of effort is a critical component to success in the fight against corrosion and while corrosion control is not a new concept to the Marine Corps, we live in an age where new CPAC technologies, products and procedures are developed and emerge on a constant basis. Given the operational tempo and every day maintenance challenges of I MEF organizations, it is unreasonable to expect that these new developments in CPAC can keep pace without a focused effort in the area of CPAC technology, product and procedure development. Additionally, as new technologies, products and procedures are adopted a mechanism must be put in place to ensure that these new tools in the corrosion fight are employed in a consistent manner across the scope of an organization’s CPAC effort. 2. In order to ensure that the necessary focus of effort is applied within CPAC Programs, I MEF organizations at all levels will, at a minimum assign in writing as a collateral duty, a CPAC Program Coordinator. The CPAC Program Coordinator will be responsible for coordinating the organization’s CPAC effort and will further act in a quality assurance role to ensure that CPAC Program is uniformly executed across scope of the organization’s CPAC and maintenance effort. 1003. INFORMATION RESOURCES 1. There are many sources of information regarding CPAC and associated tasks. Many of these information resources take the form of Marine Corps/Army/DoD Orders, Technical Manuals, and Technical Bulletins. Other information resources may include commercial technical manuals and bulletins; civilian-authored reference books; and scientific and informational Web Sites. Marines involved in the corrosion prevention fight should not limit themselves to one source of information and should continually seek the most up to date source of CPAC information. The list below is not intended to be all-inclusive, but provides a baseline starting point for building a CPAC library that will support the organizational CPAC Program. a. MCO P4790.2C. MIMMS Field Procedures Manual. This manual establishes policy and procedures for management of Marine Corps ground equipment maintenance. It provides the basic outline for all maintenance management and maintenance related programs. b. MCO 4790.1B. Corrosion Prevention and Control (CPAC) Program: To publish policy establishing the CPAC for Marine Corps 1-6

CPAC SOP 1003 tactical ground and ground support equipment, and to assign duties and responsibilities to accomplish the objectives of this program. c. TM 4700-15/1H. This manual will instruct users how to properly fill out forms and records associated with ground equipment. This includes such forms as Product Quality Deficiency Reports (PQDR’s) and Equipment Repair Orders (ERO’s). d. TM 4795-12/1. Describes depot corrosion control materials and procedures. This manual can be used to ensure end items received from Remote Storage Activities (RSA) and or Depot level maintenance facilities have had proper CPAC procedures applied. If equipment discrepancies are found based on the requirements of this Technical Manual, a Supply Discrepancy Report (SDR) and or PQDR should be submitted by the receiving organization through appropriate chain of command to Commander, Marine Corps Material Command with a detailed narrative of noted discrepancies. e. TM 4750-15/_. Describes camouflage paint patterns for ground equipment. Discusses methods for cleaning and preparing surfaces prior to painting, application procedures for Waterborne Camouflage Coating (WBCC), and procedures for marking and camouflaging equipment. f. TM 4795-12/1. Describes techniques and procedures and products that shall be used at the 1st and 2nd echelon of maintenance to fight the corrosion battle for Marine Corps Equipment. This manual is for use in controlling corrosion and wear on USMC equipment.(Note: This technical manual replaces TM 3080-12, which is now obsolete) a. TM 4795-34-2. Describes techniques to be used at the 3rd and 4th echelon level to fight the corrosion control battle. It includes Rust- proofing Procedures for Tactical Vehicles and Trailers. This technical manual defines types of corrosion as well as key corrosion prevention techniques and materials, material application instructions, and important application safety hazards.(Note: This technical manual replaces TM 3080-34, which is now obsolete) b. The USMC CPAC web site is also a valuable source of CPAC information. This web site requires a password for access. Instructions for obtaining a password are contained on the web site. Users can access the CPAC web site through the Marine Corps Systems Command (MCSC) web site at www.marcorsyscom.usmc.mil. Once accessing the MCSC web site, click on “SYSCOM Organizations” then click on “Corrosion Prevention and Control (CPAC)” then click on “Request for Access” and follow the directions to obtain an access password.

c. The Tri-service coatings Website provides information on approved CARC coatings at www.arl.army.mil/wmra/coatings. 1004. REPORTS AND RECORDS 1. Accurate historical information is essential to any Base-lining and analysis effort. References (a) and (d) provide guidelines and procedures for maintenance and maintenance management related record, from the equipment operator to the equipment keeping requirements. All Marines are responsible for the accuracy of CPAC records and reports. It is extremely important to the success of the CPAC Program that CPAC related information is accurately documented per reference (d). 2. Per paragraph 1001.2 proceeding, all I MEF organizations will submit the results of their annual CPAC Program equipment inspection, hereafter referred to as “Annual CPAC Equipment Report, to the Commanding General, I MEF, attention Assistant Chief/of Staff G-4/Maintenance Management Officer, (AC/S G-4/MMO, I MEF) via their respective Major Subordinate Commands (MSC(s)). The annual CPAC equipment report will be due no later than the last day of the third quarter of the fiscal year. The annual CPAC inspection may be accomplished anytime during the current fiscal year prior to that date. Separate I MEF Battalions not falling under a MSC will submit their annual CPAC Equipment Report directly to AC/S G-4/MMO, I MEF. The Annual CPAC Equipment Report format is found in Appendix A of this order. 3. Marine Corps Material Command (MATCOM) requires the operating forces to provide three reports regarding fiscal expenditures, backlog and requirements. Each quarter, all operating forces are required to submit quarterly CPAC expenditure reports. Operating forces are also required to submit projected CPAC expenditures for the next two Fiscal Years (FY), for example, projected CPAC expenditure requirements submitted in November of 2000 (FY-01) would reflect CPAC requirements for FY(s) 2003 and 2004 with backlog identified. The I MEF CPAC Coordinator will request CPAC expenditure data from I MEF organizations by message when the information is required. 1005 INTERNAL REVIEWS AND INSPECTIONS 1. Paragraph 4007 of reference (a) goes into detail concerning inspections and their value to the Commander and should be used as template for CPAC Program internal reviews/inspections. Periodic focused internal reviews/inspections provide the commander a snap shot of whether the organization’s programs, policies, practices, and staff functioning are effective and meeting Commander’s expectations and goals. Internal reviews/inspections further provide the Commander a “scorecard” to measure how the organization is performing relative to the benchmarks set by that organization. 2. I MEF organizations at all levels will incorporate CPAC Program provisions into their Internal Review/Inspection Programs

using this order and the Inspection Checklist contained in Appendix B as a basic guideline. 3. Additionally, the local Field Supply and Maintenance Analysis Office (FSMAO-2) will be requested to include analysis of organizational CPAC Programs as a matter of routine during analyses of I MEF organizations. 1006. OCCUPATIONAL HEALTH AND SAFETY CONSIDERATIONS 1. An Occupational Health and Safety Chapter will be added to this SOP in the future. 2. The health and safety of our Marines is of paramount importance and takes priority over all other garrison considerations. Reference (d) is the Marine Corps Occupation Health and Safety Program Manual and will be strictly adhered to. CPAC actions have the potential to expose Marines to hazardous materials that by their nature can adversely affect the health and safety of Marines if proper procedures are not followed when handling these materials. Though of paramount importance, past concern for the health of our Marines has resulted in unnecessary prohibitions regarding CPAC actions such as “rust busting” and spot painting. Appendix E was a study conducted by U. S. Naval Hospital regarding exposure to heavy medal particular when scraping and chipping Chemical Agent Resistant Coating (CARC) paint. The results of the study indicate that Marines may chip and scrape all types of CARC paint with hand tools without using respiratory protective equipment. In other words, Marines may “bust rust” with hand scrapers and wire brushes. Spot painting with the use of CARC, Water Borne CARC (WBCC) and Water Reducible CARC (WRCC) is permitted without the use of respiratory protective equipment within the standards of applicable Material Safety Data Sheets (MSDS) and other technical documentation. 3. Personal Protective Equipment (PPE) requirements become more stringent when powered tools and spray-painting operations are performed. Spray painting of CARC paint is not permitted at the organizational level of maintenance and may only be performed at the Intermediate Maintenance Activity; Corrosion Rehabilitation Facility located at GSM Company, 1st FSSG. For additional information regarding use of powered tools for corrosion removal see Chapter 3, Paragraph 3003.2.

CHAPTER 2

THE CORROSIVE ENVIRONMENT 2000. INTRODUCTION 1. Marine Corps Base Camp Joseph H. Pendleton, the nation's busiest military base, located 38 miles north of downtown San Diego; Camp Pendleton covers over 250,000 acres and approximately 200 square miles of terrain. The stretch of shoreline along the base-- 17½ miles -- is the largest undeveloped portion of coastal area left in Southern California. Camp Pendleton provides training facilities for many active-duty and reserve Marines, Army and Navy units, as well as national, state and local agencies. Over 60,000 military and civilian personnel work aboard the base every day. The base is the home of I Marine Expeditionary Force, 1st Marine Division, 1st Force Service Support Group and many tenant units, including elements of Marine Aircraft Group 39 and Marine Corps Tactical Systems Support Activity (MCTSSA). 2. In addition to being home-based in California, I MEF organizations constantly deploy aboard naval ships for amphibious training and exercises to other locations in the Pacific Ocean with similar environments to those of Hawaii. 3. As illustrated in the preceding paragraphs, I MEF organizations operate daily and deploy in environments that are conducive to corrosion and that present special challenges to the readiness and capability of I MEF equipment. 2001. ENVIRONMENTAL FACTORS 1. Numerous environmental factors contribute to the corrosive environment. The most commonly recognized factor in a corrosive environment is proximity and exposure to salt water and salt ocean air hereafter referred to as the “Marine Environment.” However, this is but one factor that must be considered. The following is a summary of factors that collectively contribute to the corrosive environment and that must be taken into consideration in the fight against corrosion. a. The Marine Environment. Saltwater is a naturally occurring electrolyte and promotes electrochemical corrosion, the process of changing the chemical structure of a metal or alloy due the electron flow in an electrolyte. Electrochemical corrosion is the most common form of corrosion affecting Marine Corps equipment. b. Rain. Rain is also another naturally occurring electrolyte, though not as damaging in and of itself as saltwater. However, when rain mixes with salt spray during periods of high winds it in essence becomes salt water and will promote corrosion the same as salt water.

c. Petroleum-based Products (POL). Though not commonly recognized as such, some POL(s) like hydraulic fluid and fuels can act as electrolytes and promote corrosion when in contact with metal surfaces. d. Corrosive Fluids. Fluids such as battery acid, the most commonly recognized electrolyte, and Nuclear, Chemical and Biological (NBC) decontaminating solutions are highly corrosive and promote corrosion when in contact with metal surfaces. e. Sunlight. Though not commonly thought of as a contributing factor to corrosion, sunlight will contribute to corrosion. Intense sunlight will cause protective finishes to deteriorate thereby making them less effective in protecting equipment from corrosion. Sunlight will also dry out salt spray leaving residual salts that slowly promote corrosion when dry and become very active when “re-wetted” as a result of rain. f. Wind. Strong sea breezes and winds generated by storms, topical storms and typhoons can be heavily saturated with salt spray and can force high concentrations of salt water into mating surfaces and crevices of equipment thereby promoting corrosion in hard to reach/ hard to inspect areas. 2. In order to be fully effective, a CPAC Program must take all environmental factors into consideration. Even if an organization has not deployed its equipment aboard shipping or directly exposed it to seawater, the equipment is still at risk from the overall corrosive environment. 2002. THE SCIENCE OF CORROSION 1. Corrosion. Understanding the science of corrosion is important to understanding how to combat it. Corrosion is the process of metal deteriorating or returning to its natural state. Corrosion occurs in all metals at different rates and under different circumstances. The marine environment promotes electrochemical corrosion, the process of changing the chemical structure of a metal or alloy as a result of the flow of electrons in an electrolyte. 2. Electrochemical corrosion occurs when an electrolyte is in contact with two dissimilar metals. As noted in paragraph 2001.1, seawater, salt spray, and rain are common naturally occurring electrolytes. While POL(s), decontaminating solutions, and battery acid are man-made electrolytes. Electrolytes allow an electrical current to flow between the two dissimilar metals creating a “charge” which is called a “galvanic reaction” in which one of the metals corrodes. 3. There are four elements that must be present for corrosion to occur: an anode, a cathode, an electrical path, and an electrolyte.

a. An anode is a metal that is more susceptible to corrosion. b. A cathode is a metal that is less susceptible to corrosion. c. The electrical path is the flow of electrons between the anode and cathode. d. An electrolyte is a solution capable of conducting current between the anode and the cathode. 4. During the corrosion process, a small current flows between the anode and the cathode. This current occurs as a result of the voltage potential differential that exists between the anode and cathode. This is the same process that allows a battery to produce voltage and power. The flow of current between the anode and cathode causes corrosion to occur on the anode. Corrosion on a single metal, or general corrosion is caused by formation of microscopic anodes and cathodes. 5. If the four elements of corrosion are viewed as a square, each element being one side of the square, the “Corrosion Square” must be broken in order to arrest or prevent corrosion. The Corrosion square can be broken in a number of ways. Avoiding use of dissimilar metals in the manufacturing is one way to break the Corrosion Square. However, at the operating force level, we have little control over the manufacturing process and must fight the effects of corrosion on equipment that is in our inventories. Corrosion at the operating force level must be fought by maintaining effective barriers to block electrolytic current flow. 6. Paragraph 2 of reference (e) goes into great detail on the science of corrosion and should be thoroughly reviewed by all Marines, both maintainers and operators.

CHAPTER 3

CORROSION PREVENTION AND CONTROL MEASURES 3000. INTRODUCTION 1. CPAC starts with prevention. Prevention starts with the individual equipment operator. All to often in the past, CPAC has been viewed as a “maintenance function.” If corrosion on an item of equipment has reached the point where the item must be turned into the supporting maintenance section for corrective action, it is too late and our CPAC efforts have failed. The equipment operator is the first line of defense in the battle against corrosion. Reference (e) provides detailed procedures and instructions to be employed in achieving CPAC. This chapter only summarizes the detailed information contained in reference (e), which must be used as the CPAC standard in all I MEF organizations. 3001. THE CLEANING, INSPECTION AND PRESERVATION PROCESS 1. CPAC is best achieved by equipment operator application of the three-step “CIP” process as depicted below: Cleaning_____________C Inspection______________I Perservation_______________P a. Cleaning: Removing rust, oxidation, dirt and salt and other contaminants from the surface of metal is the first step in the CPAC process. Cleaning procedures depend on the type of material to be cleaned (plain steel, Stainless steel, aluminum alloy, composite, rubber, etc.); severity of corrosion; and available cleaning equipment and materials. b. Inspection: Thorough inspection of equipment is the second step in the CPAC process. Equipment operators must assess the material condition of their equipment: look for corrosion, coating damage, trapped water, and contaminated surfaces. The frequency of corrosion inspection should increase with the operational tempo, severity of the environmental conditions, and importance of the component/vehicle. c. Preservation: Preservation of a clean, corrosion-free surface is the third and final step of the CPAC process. Preservation helps to protect equipment and parts by providing coatings, anti-seizes, sealant, and water displacing and corrosion preventive compounds (CPCs). Preservatives should be used after equipment cleaning, before and after deployment, and when an extended period of equipment storage is anticipated (unless dehumidified storage is planned). Paints such as Water Reducible Camouflage Coating (WRCARC), and their epoxy primers are certainly part of a preservation plan. These coatings provide long-term

protection, and should be used when possible instead of CPCs, which only provide short-term protection. 2. The importance of thoroughly cleaning equipment cannot be overstated. The cleaning process must be employed on a consistent basis both while in garrison and especially after field or amphibious operations. The freshwater rinse is one the simplest and effective cleaning methods employed in CPAC. The fresh water rinse should occur periodically when in garrison and as soon as practical after field operations and seawater or salt spray exposure. When using a pressurized hose to clean equipment, care must be taken not to spray electrical and communications components at full pressure. Instead, use a fine spray on components of this type, or clean them by hand. Special care must also be taken when cleaning equipment to ensure that mud, dirt, and debris are completely removed from chassis, crevices and other areas of equipment where these types of material can build up. Additives are available for use with freshwater to help neutralize salt more efficiently. However, not all work well, and some even accelerate corrosion on metals such as aluminum, so care must be taken when using additives during freshwater rinsing. Understandably, when embarked on amphibious or other ships or when in the field, freshwater may not be available in the amounts necessary. This increases the importance of other corrosion control measures such as coating preservation and the use corrosion preventive compounds. 3. Thoroughly sealing equipment to keep water and moisture out is also a simple and effective corrosion control measure that can be employed for items of equipment such as ordnance vehicles, communications equipment, engine and transmission housings, and other types of closed components. When it is impractical to seal an item, or when the chance of obtaining an effective seal is low, every effort must be made to drain entrapped water at the lowest point in the equipment. If the design of the equipment makes it susceptible to water collection and retention and does not provide for a means of draining entrapped water at the lowest point, a Product Quality Deficiency Report (PQDR) should be submitted in accordance with the current edition of MCO 4855.10_. Mating surfaces switches, covers, and holes for fasteners are places where sealant should be applied. The choice of a sealant depends on where and how it will be used, the types of fluids it may come in contact with, the operating temperature of the sealed component, and the amount of routine maintenance normally performed inside the component. Sealing procedures will normally be accomplished at the organizational level of maintenance or higher. 4. The most corrosive environments that USMC ground equipment is exposed to are beach operations, Landing Craft, Air Cushioned (LCAC) operations, and transport in the well decks of U. S. Navy amphibious shipping. Operations in these types of environments are inherent in our mission. For many years there was, little Marines could do to prevent or even mitigate corrosion from occurring as a result of operating in these type environments. However, with the introduction and approved use of new commercial additives and

inhibitors, corrosion can be prevented or at least mitigated through careful use of additives and inhibitors. 5. Protection of the equipment from the weather is another way to prevent corrosion, prolong service-life and reduce maintenance requirements. Keeping vehicles or equipment stored under simple open-sided covered structures can reduce exposure to rain and direct sunlight and acts to preserve the integrity of corrosion coatings as well as preventing water from accumulating in equipment. Tarps, canvases or other materials can also be used to protect equipment. However, strict guidelines must be developed and applied to ensure that “tarped” equipment is not allowed to sit under wet tarps. Tarps can in fact promote corrosion if allowed to cover equipment while wet. 3002. SPECIAL CONSIDERATIONS FOR DEPLOYED OPERATIONS 1. A mentioned above, deployed operations pose special challenges relative to CPAC. The deployed environment, lack of facilities, lack of time and the non-availability of freshwater for wash downs all contribute to the CPAC challenge. These challenges can sometimes be overcome by careful pre-deployment post-operation maintenance recovery planning. 2. Careful pre-deployment preparation of equipment for the corrosive environment is also of paramount importance in preventing or mitigating corrosion while deployed. Appendix B of reference (e) provides a detailed checklist of pre, during and post deployment actions that should be followed by deploying organizations. 3. Marine Expeditionary Unit (MEU) Equipment Rotation. Due to extremely corrosive environment encountered during deployment aboard amphibious shipping, equipment rotations take on added importance as a “preservation measure”. Accordingly, MEU Command Element Non-Table of Equipment, Ground Combat Element (GCE), MEU Service Support Group (MSSG), and Air Combat Element (ACE) motor transport, Heavy Engineer Equipment, Ordnance Vehicles, Howitzers, and Utilities equipment will be rotated. Table of Equipment items assigned to the MEU Command Element will, at a minimum, be inducted in for corrosion corrective maintenance and painting every 24 months. 3003. CORROSION CORRECTIVE MAINTENANCE AND REHABILITATION 1. Despite our best efforts, equipment will corrode and require some level of maintenance or rehabilitation. 2. Organizational Level Corrective Maintenance. The equipment operator and the organizational level maintainer accomplish organizational level corrective maintenance relative to CPAC. Equipment operators remove rust and corrosion and apply protective coatings through spot painting and application of other anti-corrosion compounds. The organizational level maintainer may also

remove rust and corrosion that is more extensive and requires the use of powered grinders and the like. CPAC Tool Kits have been fielded to all I MEF organizations. These kits are Type II items and may be purchased by unit Commanders in higher quantities than were initially issued. The CPAC Tool Kit is an accumulation of tools and miscellaneous items, produced by a variety of manufacturers that are used to prepare metal surfaces for protective coatings, dependant on the type metal, and the item being protected. The items in this kit comply with Environmental Protection Agency (EPA) requirements for this type equipment for handling Hazardous Materials. The kit consists of a plastic container, electric, or pneumatic grinders, vacuum cleaner, needle scaler, and hazardous waste disposal bags. The vacuum cleaner evacuates dust, paint chips and particles from the operating surface area into the hazardous material disposal bags contained within the plastic container. Other power tools, not components of the CPAC Tool Kit, may also be used providing that proper PPE is used/worn. The organizational level maintainer may also replace certain corroded components, fasteners, and sheet metal components providing these type components are within authorized echelons of maintenance found in applicable technical manuals and publications. 3. Equipment that is corroded to the point that it exceeds organizational level repair capabilities is normally evacuated to the intermediate level of maintenance for corrective maintenance or rehabilitation. 1st Maintenance Battalion performs intermediate level corrosion corrective maintenance and rehabilitation for California based I MEF organizations through its Intermediate Maintenance Activity, Corrosion Rehabilitation Facility or outsourcing. Chapter 4 of this SOP addresses intermediate level corrosion corrective maintenance and rehabilitation in detail.

CHAPTER 4

CORROSION REHABILITATION PROGRAM 4000. INTRODUCTION 1. When preventive measures fail and corrosion damage occurs to equipment, corrective maintenance action must be taken. Corrective maintenance actions occur at both the organizational and intermediate levels of maintenance. 2. The IMA CRF’s primary goal is to provide a cost and time effective corrosion rehabilitation program as an alternative to transporting equipment to and from the Marine Corps Logistic Bases, Albany, Georgia and/or Barstow, California. The IMA CRF accomplishes its mission by: a. Minimizing maintenance cycle time for equipment inducted for rehabilitation. b. Providing quality Intermediate Maintenance Activity support. c. Providing technical advice to Major Subordinate Commands (MSC) on matters related to corrosion protection and prevention. 3. IMA CRF repairs equipment and vehicles from all commodities; communications, engineers, motor transport, and ordnance. The facility repairs body components that would normally be replaced, restoring them to the original specifications. This process not only saves the owning unit precious maintenance and operational funds, but also enables owning unit maintenance personnel to concentrate their efforts on other maintenance tasks. The IMA can usually make the necessary repairs and return the equipment to “like new” condition even when corrosion damage is extensive. 4. Marine Corps Logistics Bases (MCLB) or local civilian contractor’s are responsible for supervising and executing all work conducted. Marines assigned to IMA CRF provide quality assurance and contract supervision. MCLB and civilian contractor’s provides all necessary labor, management, supervision, tools, equipment, and supplies outside of the IMA CRF’s capabilities. 5. All maintenance performed at the IMA CRF will be conducted in accordance with the Statement of Work (SOW) contained within the Corrosion Contract issued by the Regional Contracting Office. 4001. CORROSION REHABILITATION FACILITY (IMA CRF) 1. The IMA CRF falls under administrative and operational control of General Support Maintenance Company (GSMCo), 1st Maintenance Battalion, 1st Force Service Support Group. However, on matters dealing with the monthly service contracts and the processing of

the contractors monthly invoices, the Contracting Officer’s Representative (COR) is authorized direct liaison with 1st Maintenance Battalion, Maintenance Operations Section (MOS) Fiscal and the Regional Contracting Office. 2. IMA CRF: The IMA CRF is responsible for the smooth and efficient operation of all maintenance and administration functions. The IMA CRF may make direct liaison with the Maintenance Operations Section, and Regional Contracting Office on matters relating with contract payment and invoices for services performed at the IMA CRF. The IMA CRF COR endorses all service contracts and monthly invoices and accepts equipment on behalf of the government. 3. IMA CRF Quality Assurance: Quality Assurance Inspections performed on equipment both in the active maintenance phase and upon completion of corrosion rehabilitation work. The inspectors will ensure work meets the standards set forth in the SOW and applicable orders or directives related to specific items of equipment. 4. IMA CRF HAZMAT NCO: The Hazardous Material (HAZMAT) Non-commissioned Officer (NCO) works directly for the IMA CRF Floor Chief. He/she is responsible for the safe handling and disposal of all waste products at the IMA CRF, as well as the disposal of recyclable items, scrap metal, empty paint cans and empty cardboard boxes per reference (c). The HAZMAT NCO is responsible for the respiratory management program within IMA CRF per reference (d). He/she will ensure that all personnel assigned to IMA CRF have completed and passed the appropriate medical screening. The HAZMAT NCO will provide the necessary training to all personnel assigned to IMA CRF on all safety and hazardous materials/waste handling, use and disposal. The HAZMAT NCO will coordinate IMA CRF hazardous Material/Waste issues with the GSMCo HAZMAT Representative and the 21 Area Camp HAZMAT Supervisor. 4002. CORROSION REHABILITATION NOMINATIONS 1. The amount of equipment that may pass through the IMA CRF in a given Fiscal Year is predicated by the amount of CPAC funding provided to I MEF by Marine Forces, Pacific. The I MEF Headquarters will provide the amount of funding available for IMA CRF operation to the Commanding General, 1st FSSG at the beginning of each Fiscal Year. Once the funding line has been established, the AC/S G-4, 1ST FSSG will allocate corrosion rehabilitation quotas to each MSC during October of each fiscal year and provide those quotas to the IMA CRF. The IMA CRF will ensure that MSC’s do not exceed their allotted quotas. The IMA CRF will also monitor MSC quotas to ensure that maximum advantage is being taken of quota allocations. I MEF organizations will submit equipment nominations to the IMA CRF via respective MSC’s. Nomination lists are due to IMA CRF by the 20th of the each month per the example in Appendix D. Nominations may also be submitted by electronic mail (e-mail). The IMA CRF will inform the AC/S G-4, 1st FSSG if allotted quotas

are exceeded or if they are not being filled on an as required basis. 2. Guidelines for corrosion rehabilitation quotas and nominations are set forth by the AC/S G-4/MMO, I MEF. Request for changes to total MSC quota allocations must be submitted to the AC/S G-4/MMO, I MEF citing ample justification as adjustment of MSC quotas may impact another MSC. Once each MSC has allocated its quotas to individual subordinate elements, changes to an individual unit’s nomination quotas must be submitted to the IMA CRF via the respective MSC. 3. I MEF corrosion rehabilitation eligible equipment is divided into equipment sizes based on cubic feet and not equipment characteristics. The new Ultra Light category is for the payment of the contractor only and does not affect the old or existing quotas listed in paragraph 4. Equipment size classifications are depicted in Figure 4-1. The AC/S G-4/MMO, I MEF will publish a TAMCN equipment size classification category message at the beginning of each fiscal year. CLASSICATIONS

DEFINITION EXAMPLE

ULTRA LIGHT Less than 300 cubic feet Panels, Braces, Ring Mounts, M116 Trailers

LIGHT Greater than 300 cubic feet but less than 1000 cubic feet

Figure 4-1.—Size Classifications

4. In instances where I MEF organizations request corrosion rehabilitation services for individual parts or components not associated with a Principal End Item (PEI), an ERO and Service Contract will be assigned for the job. The size classifications and number of items on each ERO/service contract will be agreed upon by the IMA CRF and contractor based on the existing size classifications delineated in the SOW. 5. If an allotted quota cannot be met I MEF, organizations may substitute an item of like size or smaller. Equipment substitutions must be coordinated through the respective MSC after liaison has been made with the IMA CRF.

6. Requests for scheduling additional equipment into IMA CRF above a unit’s allotted quota will be submitted to the AC/S G-4/MMO, I MEF via the respective MSC and after liaison with the IMA CRF. 4003. CORROSION REHABILITATION MAINTENANCE PHASES 1. Induction and Acceptance Phase. a. Administration. All requests for corrosion rehabilitation, to include body repair, will be supported by an Equipment Repair Order (ERO) and CPAC Equipment Induction Inspection Form (APPX E). Only one item per ERO is authorized for induction. Administrative requirements are as follows:

i. A 2nd echelon ERO must be open in MIMMS AIS.

ii. Owning units will prepare a courtesy 3rd echelon ERO and bring a copy of the Daily Process Report (DPR) displaying the open 2nd echelon ERO. Ensure the ERO lists a current point of contact with phone numbers that can be reached during and after working hours.

iii. Owning units will provide the Equipment Record Jacket, NAVMC 696, for motor transport and engineer equipment at time of induction.

iv. Ensure a current Unit ERO Authorization letter is on hand at the IMA CRF.

v. When owning units drop off equipment that must be transported to the IMA CRF, they must accompany the equipment so that it can be inspected/inducted and all paper work completed (CPAC Equipment Induction Inspection Form). Only then will the equipment be inducted into the IMA CRF. This administrative process must be accomplished; there will be no exceptions to this provision. If an owning unit has to pick up equipment, that requires transportation; the paperwork/ERO needs to be closed out prior to picking the equipment up from IMA CRF. Owning units may close out the paperwork/ERO during normal working hours at any time after all completion of the corrosion rehabilitation process. Owning units need not wait until the day prior to pickup to close out the paperwork/ERO. Equipment will not be released to the owning unit until the paperwork/ERO is closed. Owning units who need to either deliver or pick up equipment from the IMA CRF after normal working hours must make liaison with the IMA CRF prior to either action.

vi. Once an item arrives at IMA CRF for induction, a joint inspection will be conducted using an Equipment Induction Inspection Form as depicted in Appendix E. If the equipment passes inspection, the ERO and the equipment will be accepted. If equipment fails, a copy of the form will be made available to the owning unit at which time the owning unit has the option of

correcting noted discrepancies on-site or returning the equipment to the owning unit’s maintenance facility. Repairs that are made on-site must be completed within 48 hours or the equipment must be removed and repaired at the owning unit’s facility. Once the equipment is repaired, it will be re-inspected and inducted.

vii. Upon acceptance of equipment, a locally generated tag will be filled out and attached to the equipment. The equipment will be stored in the Short Space lot until it enters the IMA CRF shop space. The Inspection Sheet will be turned into the Data Clerk who will input the information into the database, assign a contract number, and give a Request for Services Sheet to the contractor. b. Equipment preparation requirements. The equipment owner is responsible for preparing equipment for induction into the IMA CRF. Equipment preparation requirements are as follows:

i. All equipment must be operational. Motorized equipment must be able to move under its own power and brakes must be fully operational. If the equipment malfunctions in the repair cycle, the owning unit will be contacted to make repairs.

ii. All 1st echelon preventative maintenance (except oil can maintenance) will be performed prior to induction. Note: 1st echelon PM can be performed while the equipment is in Short Space Status (weekly PM's). Units must ensure the equipment has no leaks or seeps. The equipment must be clean to include suspension, frame and the underside of engine covers must be free of grease and oil.

iii. Fuel tanks for all Motor Vehicles and Heavy Equipment must be 3/4 full.

iv. All generators, welders, and air compressors must be empty of fuel (see paragraph 4003.1.b(5) below).

v. Fuel carrying equipment must have a current gas free engineering initial testing certificate (Six-con tanks, M-970 and M-49 Re-fuelers) from the MCB Camp Pendleton, Safety Office. This includes all generators, welders, and air compressors.

vi. Underside hood insulation on all On M939 5 ton trucks must be removed prior to induction into the IMA CRF (this allows easier access to the under side of the hood and helps ensure better undercoating).

vii. All SL-3 and Operational Vehicle Mobile (OVM) items must be removed prior to induction including: all canvas, canvas framing, exterior straps, tie-downs, spare tires, and seat cushions.

viii. All radio-related items must be removed from Communications Vehicles.

ix. The IMA CRF will require access to the inside of all shelters and containers. Contents either have to be removed for security purposes or arrangements made with the IMA CRF to have owning unit organization personnel on site at IMA CRF when the repairs are being made.

x. Owning units inducting equipment with special or unique applications will provide a knowledgeable technician or working party to ensure all special requirements applicable to the equipment are addressed during the corrosion rehabilitation process. Some examples of equipment falling into this category are howitzers, radar, and satellite dishes, applique armor plating and ordnance vehicles. 2. Active Maintenance Phase. During this phase of the corrosion rehabilitation process, corrosion repairs are accomplished. Owning units inducting equipment will provide a knowledgeable technician or working party to assist with the corrosion repairs that are conducted at the IMA CRF (this will be coordinated between the owning unit and the IMA CRF Maintenance Chief/Assistant Maintenance Chief/Floor Chief during the induction phase). MIMMS AIS Job Status (12), Repairs in Progress, will reflect on the DPR. During this phase, Marines assigned to the IMA CRF continuously monitor equipment at each station within the repair cycle. Once equipment is corrosion rehabilitation is completed, IMA CRF Marines will perform Quality Assurance Inspections. a. Replacement Parts: Although the contractor is required to supply the material to fabricate and repair the equipment processed at the IMA CRF, in some cases the government will supply the replacement parts if it is not economical or safe for the contractor to fabricate them, or when the contractor is unable to purchase parts such as 5 ton tuck hood hinges, windshield assemblies, hardback rear windows and the like. Items determined to be beyond repair will be brought to the attention of the owning unit who is responsible for requisitioning replacement parts. The owning unit should attempt to get all body components repaired at IMA CRF before requisitioning a replacement. b. Non-Repairable Equipment: If an item of equipment is determined to be a candidate for washout, a IMA CRF Letter of Unserviceable Property (LUP) will be provided to the owning unit. The owning unit will deliver the LUP to the appropriate Intermediate Maintenance Company and coordinate submission of the Recoverable Item Report transaction (WIR). c. Deadlined or Inoperative Equipment: In the event that an item of equipment becomes deadlined during the corrosion rehabilitation cycle, the owning unit will be contacted and take whatever actions necessary to repair the item. If equipment cannot be repaired on site, it will be removed from the maintenance cycle. The ERO will be placed in unit recall status for no more than 15 days to allow the owning unit to make repairs and return the equipment. If it is not likely that the equipment can be repaired

in a reasonable amount of time, the owning unit may substitute a like item or the ERO will be closed. 3. Maintenance Close out Phase. The close out phase begins when the Government’s Final Inspector has accepted the item, and signs for the equipment on behalf of the U.S. Government. At this point, the equipment is ready for delivery to the owning unit. The following actions occur during this phase: a. The IMA CRF will complete all administrative actions required to close out the corrosion rehabilitation process such as MIMMS AIS transactions, and updating equipment records. b. The owning unit is notified that their equipment is ready for pick up. Due to IMA CRF's limited storage space, every effort must be made by the owning unit to pick up their equipment in a timely manner. Barring inclement weather or operational demands beyond the owning unit’s control, the owning unit has 7 working days to pick up their equipment. c. When the owning unit picks up the equipment, a Quality Assurance Card will be provided for each item repaired through the IMA CRF. The Quality Assurance Card is a vital tool in tracking and assessing quality assurance. Owning units will complete the Quality Assurance Card and either mail it to the 1st Maintenance Battalion Maintenance Operations Section or submit it via the 1st Maintenance Battalion Maintenance Operations Section web site.
